TETHERED bacteria1 rotate at the angular velocity at which the torque generated by the flagellar motor2 is balanced by the torque due to the viscous drag. In general, M = bηΩ, where M is the torque, η is the viscosity, Ω is the angular velocity, and b is a coefficient which depends on the size and the shape of the cell, the position of the axis of rotation, and the distance between the cell and the wall. For a sphere of radius a (not too close to the wall) M = 8πηa3Ω (ref. 3). Viscous forces… CONTINUE READING
